(Cl. 19--98) ABSTRACT OF THE DISCLOSURE A casing for the flats of a carding machine consisting of two solid detachable side panels, a detachable lid and two supporting braces.

The side panels are secured to the carding machine by pins on the machine brackets and holes in the panels, and are fixed with respect to the sheet with belts by means of slots in the supporting braces and projections on the side panels.

The lid is secured to the supporting braces and has a collapsible part and a rotating segmental cover, arranged at opposite ends of the lid.

The present invention relates to casings for flats of carding machines used in the textile industry.

Known in the prior art are casings for flats of carding machines consisting of two parts articulated with one another, the framework of each part being made nondetachable. (See, for example, a catalogue of the Sacm Society of Alsace on the RWN carding machine and Textile Recorder, N. 941, 1961, pp. 62-63.)

A disadvantage of the known casings for flats of carding machines is the cumbersome nature of such frameworks which interfere with and hinder the servicing and repairing of the carding machines.

A non-detachable casing requires considerable time for adjusting, which is necessary for its setting up and dismounting, and requires as well free space in which to place the casings which are being disassembled.

An object of the present invention is to provide such a casing for flats of carding machines which does not require too much space when being disassembled, and which is trouble-free in regard to setting up.

Another object of the invention is to provide such a casing which is relatively easy to service and which permits the adjustment of the machine without dismounting the main parts thereof.

In accordance with these and other objects, the casing for flats of carding machines is made, according to the invention, dismountable, and comprises two supporting braces the shape of which correspond to that of the slack sheet with flats, and which are attached to the machine brackets, two side panels and a lid secured to said supporting braces, said lid having a segmental cover and a collapsible end part.

The segmental cover of the lid is expediently secured on the axle of the flats stretching roller, and each side panel is provided with holes for securing the side panels to the machine brackets and with two projections by the aid of which said panel may be fixed in slots provided on the supporting braces.

Thus, the proposed casing for flats of carding machines prevents the penetration of dust into the surrounding area during the operation of the carding machines whereas the States Patent 3,375,555 Patented Apr. 2, 1968 detachable construction thereof insures the rapid setting up and dismounting without appreciable loss of time, and does not require considerable areas to place the casings when servicing and repairing the carding machines.

The invention will be further described in conjunction with one embodiment of the casing for flats of carding machines and the attached drawings, in which:

FIG. 1 schematically shows the arrangement of the casing for flats, according to the invention, as viewed from the left side of the carding machine;

FIG. 2 is the plan view of same;

FIG. 3 schematically shows the arrangement of the casing for flats, according to the invention, as viewed from the right side of the carding machine;

FIG. 4 schematically shows the arrangement and fixation of the braces and side panels of the casing, according to the invention.

The casing 6 covering flats 7 is arranged on a carding machine covered from the left side with guards 1, 2 and 3 (FIG. 1) and from the right side with guards 4 and 5 (FIG. 3).

The casing 6 is made detachable and consists of two side panels 8 and 9 (FIG. 4) covering the flats from the right and left sides, a lid 10 (FIG. 2) covering the flats from the top, and two supporting braces 11 and 12 (FIG. 4) to secure side panels 8 and 9 and said lid 10.

The supporting braces 11 and 12 have the shape of a slack sheet with flats, and are mounted on brackets 13 and 14 of the carding machine.

To secure the side panels 8 and 9 to the supporting braces 11 and 12, the latter are provided with two slots 15 and 16, respectively.

Each of side panels 8 and 9 has a hole 17 and 18 to secure said panels to the brackets 13 and 14 of the carding machine, and two projections 19 and 20 are provided on the side panels by means of which the side panels 8 and 9 are fixed in slots 15 and 16 respectively of supporting braces 11 and 12.

The shape of the side panels 8 and 9 differs as shown in FIG. 4, which depends upon the mutual arrangement of the working members of the carding machine.

The lid 10 (FIGS. 1 and 3) has a segmental cover 21 and collapsible end part 22.

The collapsible end part 22 is articulated with the lid 10 by means of a hinge joint 23, and the segmental cover 21 is secured on the axle of the stretching roller 25.

Each bracket 13 and 14 is provided with a pin 26 (FIG. 4) on which the side panels 8 and 9 are secured by means of nuts 27.

The lid 10 is secured to the braces 11 and 12 by means of screws 28 (FIG. 2).

During the operation of the carding machine, the litter accumulated within the region of the flats 7 is spilled out onto the lid of the dismountable cylinder of the carding machine on turning the segmental cover 21 (FIGS. 1 and 3) and is removed therefrom by any of known means.

For the general cleaning of the carding machine, the side panels 8 and 9 (FIG. 4) are removed; to this effect the nuts 27 are unscrewed, the panels 8 and 9 in the lower part are displaced to such an extent that the pins 26 are disengaged by the holes 17 and 18 after which the projections 19 and 20 are withdrawn from the slots 15 and 16 of the braces 11 and 12.

The removal of the side panels 8 and 9 permits access to the flats 7 for cleaning, adjusting and checking thereof.

When it is necessary to change flats, the lid 10 as well as the supporting braces 11 and 12 may be removed.

The availability of the collapsible end part 22 makes it possible to change flats without removing the lid 10 as well as to check the state of the sheet with flats, their sharpness and the degree of cleaning from wastes.

Accordingly, the detachable casing contributes to the trouble-free servicing of the machine in the zone of the main cylinder-flats, to the changing of setting between the furniture of the sheet with flats and the furniture of the main cylinder, to the checking of the state of flats, the machine brakes etc., without removing the whole casing but only its side parts 8 and 9.

The casing for flats creates additional aerodynamic resistance impeding the exit of the contaminated air from the region of the main cylinder-flats.

When describing the above embodiment of the invention, a certain concise terminology is resorted to for the sake of clarity. However, the invention is not limited with the terms so selected, and it should be borne in mind that each term embraces all equivalent elements operating in the same manner and used for solving the same problems.

Though the present invention is described in accordance with a preferred embodiment thereof, it is to be understood that modifications and variants may be used Without departing from the spirit and scope of the invention as those skilled in this art will readily understand.

These modifications and variants are considered as falling within the spirit and scope of the invention as defined in the appended claims.

What is claimed is:

1. A casing for a textile carding machine for enclosing the flats thereof which pass on rollers of said machine and have upper and lower reaches, said machine having a frame supporting said flats and a pair of brackets secured to the frame and having pins mounted thereon, said casing comprising a pair of side panels laterally enclosing the flats, each panel being provided with holes for engaging said pins, each said panel having an upper edge which conforms to the shape of the upper reach of the flats passing on the rollers, said panels including projections extending therefrom, a pair of braces having the shape of the upper reach of the flats, said braces being provided with slots and the respective side panels secured to said braces by engagement of said projections in said slots, a lid secured to said braces and covering the flats, said lid including a segmental cover secured to one of said rollers to provide access to said flats and a collapsible end part hingedly connected to said lid for providing access to flats without removal of said lid.

2. A casing as claimed in claim 1, wherein the segmental cover is pivotably secured to said one roller for rotation above the axis thereof;
